the like.

The object is to provide means for actuating the brake bar to cause itto enter between the spokes of a wheel when it is desired to stop orcontrol the speed of the car.v

The invention consists of certain novel features of construction andcombinations of parts which will be hereinafter described and pointedout in the claim.

In the accompanying drawings :Figure 1 is a view in side elevationshowing the invention applied to a car; Fig. 2 is a vertical sectionalview on the line 2-2 of Fig. 1; and Fig. 3 is a perspective view of theinvention.

A, represents the car and 1, 1 are the wheels. Connected to andextending longitudinally of the car body is a bar 3, upon which ismounted hangers 4t, 4. The hangers are connected to the bar by means ofkeys 5 and bolts 6, so that the hangers will remain in position.

A brake bar 7 is provided with a crosshead 8, which cross-head isjournaled in the hangers 4.

A lever 9 is fulcrumed between uprights 10 connected to the bar 3.Chains 11, 12 are connected to the lever at diagonally opposite points,and the other terminals of the chains are connected to the cross-head 8.

When the lever 9 is drawn downward the chain 12 will cause thecross-head 8 to be Copies of this patent may be obtained for rotatedthereby moving the brake bar 7 to a horizontal position and between thespokes of the wheel 1, where it Will be held until removed.

To remove the brake bar 7 from between the spokes of the car wheel. thelever 9 is forced upward, and the chain 11 will be drawn taut, so thatas the lever is moved upwardly the cross-head 8 will rotate and withdrawthe brake bar from the wheel.

The brake bar 7 is normally in a vertical position, but upon theactuation of the lever 9 in a downward direction the brake bar willimmediately be caused to move to a horizontal position and forcedbetween the spokes of the wheel.

From the foregoing it will be seen that a very simple apparatus has beenprovided for braking mine cars, and as the device consists of few parts,the parts can be assembled or replaced very readily.

I claim i In a brake, the combination with a car body having wheelsthereon, of hangers mounted on the car body, a brake bar journaled inthe hangers and maintained normally in a vertical position, a leverpivotally mounted on the car body, and flexible means connected to thelever and brake bar for causing the bar to be actuated upon the movementof the lever to throw the bar either to a horizontal position to engagea wheel of the car or cause the bar to be swung from the horizontalposition to a vertical position.

In testimony whereof I aflix my signature, in the presence of twowitnesses.
